I would like to present the possibility of the same God revealed more clearly through Jesus.All Monotheistic religions believe in the same God But Abraham had a "more clear" picture of God and of his work and his will for the earth than his Fathers religion.
Moses was given a clearer picture still of God.
Moses gave the law which by outward appearance was good but
it was still not a clear picture.
John 10:8 All that ever came before me are thieves and robbers: but the sheep did not hear them
Jesus came to reveal the truth,that God is not angry with his creation,in fact he loves the world(not the world system)so much that he was willing to offer up his own son so that his creation could come back to him.
Most who come after Jesus are robbers and thieves also
and end up tainting the purity of the gospel he preached and I would rather not name any specific religions.
